Question

x~B(10,0.5) p(x>2)

Answer #1

Answer :

P(X>2) = 0.9453

Explanation :

Let X ∼ B(5, 0.3). Determine:
(b) P(X < 2);
(c) P(X > 2);
Let X ∼ P0(2.1). Determine:
(a) P(X = 5);
(b) P(X < 3);
(c) P(X ≥ 3);
(d) E(X);
(e) var(X).

given P(x)= 2(x-1)(x+1)^2(x+2) answer the following a) what is
the leading term of P(x) b) what is the degree of p(x) c) as x
approaches infinity, the function P(x) _____ d) as x approaches
negative infinity, the function P(x)______ e) how many turning
points does it have? f) what are the coordinates of the x
intercepts? g) find the coordinates of the P intercepts

Let f(x)=(1/2)(x/5), x=1,2,3,4 Hint: Calculate F(X).
Find; (a) P(X=2) , (b) P(X≤3) , (c) P(X>2.5), (d) P(X≥1), (e)
mean and variance, (f) Graph F(x)

true or false:
a)Var(X)=E(X^2)-E(X)^2) is always true
b)if A and B are dependent then P(A interesection B) -
P(A)P(B)=1
c)one of the desavantages of the average is it small sensibility at
data change
d) Pearson coefficient does not indicate the assimetria of a
empiric distribution

A = {1, 2} and B = {α, β, δ}
Find B x P(A)
where P(A) is the power set multiplied by cross product of
B.
I know that P(A) = {∅, {1}, {2}, {1, 2}}
Explanations along with the answer would be helpful! Thanks
